Specification of Letters Patent.

Patented Sept. 36, 1913.

Original application filed .Tune 26, 1911, Serial No. 635,366. Divided and this application filed. December 20, 1911. Serial No. 666,943.

To all whom it may concern Be it known that I, LESLIE W. MORTON, a citizen of the United States, residing at Canton, in the county of Fulton and State of Illinois, have invented certain new and useful Improvements in Rail-Drill Drives and Frames Therefor; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to drilling machines, and it particularly relates to an im proved mechanism for operating rail drills, and the subject matter thereof originally formed a part of my application, Serial #635,366, and is a division thereof.

An object of this invention is to provide an improved jointed rail drill carrying and operating mechanism which is capable of being adjusted in various positions, where by the drilling tool may be shifted without moving the support which carries the drilling mechanism.

Another object of the invention is to provide a mechanism of this character which is strong, durable, simple of construction and operation, and thoroughly eflicient.

Other objects and advantages may be recited hereinafter and in the claims. 7 In the accompanying drawings, which supplement this specification, Figure 1 is a side elevation view of the mechanism. Fig. 2 is a detail view of the lower end of one of the depending frame members. Fig. 3 is a vertical sectional view through one of the bearing members and its adjuncts. Fig. l is a vertical sectional view through other of the bearing members and through the upper portion of the depending frame. Fig. 5 is a sectional view on the line 55 of Fig. 4. Fig. 6 is a sectional view on the line 66 of Fig. 4, and Fig. 7 is an elevation view, in detail, of an improved form of combined bearing and journal, which also forms a connection for certain other elements of the device.

Referring to the drawings, in which similar reference characters correspond with similar parts throughout the several views: the reference character 1 designates the support, which consists of a substantially horizontal base having vertical arms or standards extending upward, in parallel spaced relation to each other and carrying collars or journal bearings (not shown), in which a driver shaft 2 is mounted for rotation, said driver shaft being connected with any proper source of motive power (not shown). A beveled gear wheel 3 is secured on the shaft 2, between the vertical sides of an inverted-U-shaped bearing member 4: which is pivotally mounted on the shaft 2, between the standards 1. The upper portion 5 of the U-shaped member 4% is substantially horizontal, when in normal position, and is centrally apertured for the reception of a combined journal and bearing element 9, of similar construction as the element 25 shown in Figs. 4 and 7; this element 9 being provided with a head, which is seated under the bearing element 5, and with a journal element 9 which extends through the bearing element 5, being screwed into an element 6, of a journal bearing 8 as shown in Fig. 3.

Through the central aperture of the element- 9, extends a shaft 10, which carries a gear wheel 10 and a gear wheel 11 on its opposite ends; the gear wheel 10 being in mesh with the gear wheel 3, and the gear wheel 11 being in mesh with a gear wheel 12 which carries a shaft 13, the latter being journaled in the journal bearing 8 which is formed integrally with the vertical member 7 and with the horizontal member 6.

An element of similar construction to that which is shown in Fig. 3, consists of a journal bearing 14:, and an L-shaped supporting and connecting element, the vertical and horizontal portions of which are designated 15 and 16, respectively. The shaft13 extends through and has its bearing in the elements 1 1 and 15, while the member 25 is secured, by means of its screw threads, to the element 16, thereby forming a pivotal connection or journal, on which is seated an inverted-U-shaped hanger or bearing member, the latter consisting of depending arms 18 connected by a substantially horizontal plate 17 said plate being seated upon the head or flange element of the member 25 and supported thereby. A short vertical shaft (not shown), is journaled in the member 25, and carries a bevel gear wheel 23 and a bevel gear wheel 24, the latter meshing with a bevel gear wheel 26 which is secured on the end of the shaft 13 opposite to the end on which the gear 12 is seated.

The lower end portions of the elements 18 are a-pertured for the reception of a shaft 36, having bevel gear wheels 38 and 39 se-' cured on its respective ends. A bevel gear wheel 22 is mounted on the shaft 19 and adapted to rotate thereon, said bevel gear being in mesh with thebevel gears 23 and 8S. The strut or frame member-37 is secured to the members 21 by means of bolts 10, and it is obvious that the strut 35 is susceptible of being similarly connected or secured; however, it is clearly obvious that the end portions 20, of the frame may be secured in fixed relation with each other by means of the shaft 19, in which case, the wheel 22 would not be fixed on the shaft 19, but would be free to rotate thereon; whereas, if the members 21 are held in fixed position by the member 35, the wheel 22 may be secured on the shaft 19 and rotate therewith. It is also obvious, that the gear wheel 3 may be rotated by any proper means, independently of the shaft 2. The elements 20 and 21 of the frame are connected by or formed integrally with the diagonal or outwardly flared portions 3 1. The lower ends of the depending bars 21 are formed with enlarged cylindrical portions 11, which are apertured at 12, to form a bearing in which is j ournaled a gear wheel 39 meshing with the gear wheel 39, for

driving the drill shaft 39 which carries the drill 39 In operation, the supporting bracket 1 is stationed and secured upon a car, truck or other proper support (not shown), above the level of the rails which are to be drilled, said support being of such height that the center of the portions 41 are on or slightly below the level of the portion of the rail which is to be drilled, when'the frame 21 is in vertical position. It will be seen that, by swinging the frame 21 on its pivotal point at 19, the center at 11 will be moved upward, as well as in a lateraldirection, so that theiholcs may be drilled at any desired point in the rails. It will also be seen that by swinging the members 7, 13, let, 15 and 21 around the axis of the wheels 10 and 11, the direction of the drill may be 27, having its ends fitted in the enlarged openings 28, in the sleeves 8 and 14. This tube is retained in fixed position relative to the sleeve 8, by any proper means, and unites therewith to form a combinedbearing and journal member, the member 14 being pivotally mountedor journaled on the sleeve 27 v and being retained thereon by means of a clamp 29, said clamp being formed with ears 30 which are apertured for the reception of a bolt l having a nut fitted thereon and adapted to coacttherewith for drawing the ears 30 into proximity, and causing the member 29 to fit tightly and securelyaround the sleeve 27 The clamp 29 isprovided with a retainer element 32 havingan arcuate or segmental groove therein, and the groove of the clamp fits snugly over a shoulder or bead 14' of the sleeve 1 1, and this retainer element prevents longitudinal movement of the tube 27 relative to the sleeves 8 and 14.

I do not limit my invention to the exact details of construction, combination and ar rangement of parts as herewith illustrated and described, but my invention may only be limited by a reasonable interpretation of the claims. V r

WVhat I claim is:

1. A drive and frame comprising a pluried by the sleeve and the parallel side Y pieces in angularly adjusted position in relatlon to each other, braces for connecting the side pieces and receiving the shaft and holding the latter in position between the parallel side pieces, the "lower ends of said side pleces belng adapted for engagement with a drill shaft to support the latter, the

shaft between the parallel side pieces having a gear upon its lower end for mesh with a gear carried by the drill shaft to rotate the latter, and means for supporting one end of the drive and frame upon aplatform.

2. In a drill driving mechanism, a supporting bracket, la rotary driver element carried thereby on a horizontal axis anda transmission mechanism mounted for angular adjustment around the axis of the driver element andincluding a plurality of intermeshing gears, a normally horizontal shaft which is mounted for's'win ing movement in a horizontal plane around a point above the driver member, a dependlng frame,
